Overview of the Opera 4 IP
The Opera 4 IP is a next generation IP voice switch for SOHO and small business applications.
The full IP internal architecture of the system allows seamless connection to VoIP networks
using IP system phones and traditional analogue phones. The Opera 4 IP, depending on its
configuration may also connect to either the legacy ISDN or PSTN public networks making it the
ideal migration platform to the next generation network for the home-based business or small
business. It connects four analogue telephones and up to 16 IP system phones to the public
VoIP or PSTN networks.
Users make or receive calls via a SIP server in the public network, or via the PSTN/ISDN
network using a simple analogue phone or an Operafone IP Executive phone or an Operafone
IP Professional phone.
The Operafone IP Executive is an advanced multi function system phone with 16 programmable
keys, 6 fixed keys, loudspeaker and a blue backlit 4-line display.
The Operafone IP Professional is an advanced multi function system phone with 6 fixed keys,
loudspeaker and a blue backlit 4-line display.
Up to sixteen of these phones may be connected locally to the Opera 4 IP system or remotely
over broadband Internet. Remote IP phones have full system functionality. The system phones
have a two-port Ethernet hub, which allows a single cable to the desktop for both the phone and
the PC.
The Opera 4 IP has a full range of pbx features including voicemail, automated attendant, least
cost routing, speed dials, address books and call lists. Features such as advanced Multi-Layer
Auto-Attendant, networking of multiple systems on different sites require the installation of a
license. Licenses can also be installed to expand the number of users on the system, the
number of trunks or the number of voicemail boxes or to network multiple systems.
